PURPOSE: A method for producing metabolic products of lactic acid, acetic acid, and mannitol by serial culture is provided to continuously product the intermediate metabolic products of high yield. CONSTITUTION: A method for producing lactic acid, acetic acid, or mannitol by serial culture of lactic acid bacteria comprises: a step of putting a medium for initial batch culture to a fermentation tank and inoculating lactic acid to the medium; a step of initial batch culture of the inoculated lactic acid bacteria; and a step of continuously culturing and producing lactic acid, acetic acid, or mannitol. The lactic acid bacteria are Leuconostoc citreum HJ-P4. The medium for initial batch culture or continuous culture contains glucose, yeast extract, K_2HPO_4, MgSO_4·7H_2O, MnSO_4·7H_2O, FeSO_4·7H_2O, CaCl_2·2H_2O, and NaCl. The medium for continuous culture additionally contains fructose. |
